Cancer vaccine trials have so far tended to employ patients in the advanced stages of their cancer. Many of the early disappointments came from vaccines targeting Melanoma (such as GSK’s MAGE-A3 and Vical’s Allovectin), perhaps this was due to a lack of effective treatment for melanoma patients, a high mortality rate among patients who are not diagnosed early, and because of spontaneous remissions noted to have taken place which perhaps indicate an immune response to the skin cancer.The problem is that melanoma are fast changing cells which can mutate faster than vaccine can initiate an effective immune response.
Research performed by GSK during the development of MAGE-A3 in phases II and III showed that the health of a participant’s immune system affects the effectiveness of the vaccine.
There was also the case of Megvax trial in melanoma which resulted in a disastrous Phase III after developers changed the adjuvant to one they believed would outperform the one used for their phase II trial. Against a backdrop of high profile cancer vaccine failures in stage three, as well as other treatments failing to gain approval, perhaps investors are right to have been a little conservative.
Despite what may be seen as a long list of problems, researchers are already on their way to producing more advanced and efficient vaccines. Next week we will be looking at the future of cancer vaccines, and one things seems very clear: it’s not the theory that to blame, it’s the environment that needs to be changed. Another is that by their very nature, tumors that have arisen have had to find ways around immune surveillance. This years' World Vaccine Congress USA will be the biggest yet, with 7 conferences forming one huge event. After much media build-up, Professor Dame Sally Davies, the Government’s Chief Medical Officer, has announced updated guidelines on low-risk drinking for the UK.
Today’s announcement has been in the pipeline since the previous government announced in 2012 it intended to have them reviewed. This update is welcome – the guidelines were last reviewed back in 1995 – and thorough, drawing on three different expert groups and multiple reviews of a wide-range of evidence. The changes are also down to a weakening of the evidence that there are health benefits to drinking alcohol – so the new version is about minimising harms, rather than considering them in addition to benefits. The difficulty with communicating about alcohol consumption is that it’s very difficult for people to measure and track what they’re drinking. And that’s before you factor in pub measures versus what people might pour themselves at home.
The main change is that the recommendation for men and women is now the same – to keep health risks to a minimum, people should drink no more than 14 units of alcohol a week. The daily limits have come in for other criticisms too – for example research published this summer, found that people who don’t drink every day (which is the majority of the population) tended to ignore the guidelines, because the advice didn’t seem relevant to them. And as we said above, the new guidelines also largely do away with the notion that alcohol is beneficial for our health. The committee also wanted to help people reduce the risks from drinking large amounts on one occasion, and they’ve addressed this in a number of ways.
And it also suggests people have drink-free days to help cut down on the amount they drink. The way the guidelines are now presented also makes it clear that 14 units per week is a limit, not a target.
And the committee has decided on a minimum risk level in context of other risks we expose ourselves to.
Finally, the guidelines also recommend that for pregnant women and those trying for a baby the safest approach is to drink no alcohol at all.
We’ve blogged about alcohol and cancer many times – especially the link with breast cancer – but here’s a quick recap. It’s been established for decades that alcohol can cause cancer, but the impact that lighter drinking has on risk has taken longer to tease apart. But more recently, it’s become clear that low level drinking (meaning around a drink a day on average) increases the risk of breast, mouth, throat and oesophageal cancers.
The extra risk for drinking at low levels is fairly small, so it probably won’t make much difference to an individual’s absolute risk of developing cancer – but over a population the size of the UK, where many people drink at low levels, it adds up to a big impact.
These figures are worked out using the same method as we’ve previously used for breast cancer and alcohol drinking – but show the risk for mouth cancer which affects both men and women. These updated guidelines are welcome – but by themselves they’re not going to solve the UK’s problems with alcohol and health.  The amount we drink in the UK is almost double what it was in 1960, so it’s also vital that the government invests in national health campaigns to provide people with clear information about the health risks of drinking alcohol, particularly at levels above these new guidelines.
But even if people know and understand the risks, they need to be in an environment that supports them to make changes. These guidelines are an important step in helping people understand – and reduce – the risks from drinking alcohol. Some quick ways to cut out units are to choose lower strength beers and wines, opt for smaller servings – or you could try a shandy or spritzer.
And if you’re drinking in a group, staying out of large rounds means you don’t have to match anyone else’s pace, and you can more easily avoid being cajoled into having a drink that you didn’t really want. And there’s something else you can do too – the CMO has also announced a public consultation to check that the guidelines are clear, easy to understand and, perhaps most importantly, useful.
Everyone has their own priorities and their own approach to risk, but along with the CMO we believe people have a right to clear information to help them make decisions about their lives. We’ve started off by estimating the underlying risk of a non-drinker in the UK being diagnosed with mouth cancer – we have to estimate this because risk of being diagnosed with mouth cancer at some stage in your life (1 in 84 for men, 1 in 157 for women) includes the whole population – from tee-totallers to very heavy drinkers. Using these estimated risks for non-drinkers, we’ve then modelled the impact of drinking at different levels using risks for men and women from a recent review of the evidence. And why the funny numbers of units?  Research, including the paper our calculations are based on, often uses grams of alcohol per day as a standard measure of drinking. I find the way sites such as this, plus the NHS and others, are spinning this is outrageous and grossly misleading and in some cases unprofessional. I would like to see the demographic breakdown as well as the diet, health and lifestyle of the individuals that took part as well as the type of drinks and sugar intake. The above study in it’s current form is too ambiguous, you can equally say that 1 out of 5 people that eat bread may develop cancer. I am very disappointed with Cancer Research aligning with what is quite simply bad science.

What any sensible person does is make sure they mitigate the risks they face to an acceptable level, whilst still living an enjoyable life. This research fails completely to address the significance of the risk identified here and basically tells you to live a long miserable life because everything is bad for you. How about making free measuring cups available in supermarkets so that drinkers can tell how to measure a unit.
For the first time, I know how many units in a bottle of wine, and the consequences of drinking it !
Thank you for your brilliant summing up of alcohol units & the risks associated with drinking in relation to mouth cancer risk. Do the studies that claim there are NO BENEFICIAL EFFECTS of moderate drinking take any account of the therapeutic value of a convivial glass of wine shared with friends at the end of a stressful day? Doesn’t the alcoholic strength of the drink have a major effect on the likelihood of developing mouth cancer?

The problem this undoubtedly poses for developers is that cancers can supress the immune system, and so the longer a patient has had cancer, the weaker their immune system may well be.
It takes time for patients to develop an immune response, and with melanoma, as well as many other cancerous cells, able to mutate quickly, it is possible that the vaccines are being out paced by the cancer. If we take suggestions of patient selection bias seriously for single-arm phase II studies, we can suggest that the immune systems of the generally healthy phase II participants produces a better response to the cancer vaccine than will be found amongst a randomly selected phase III patient pool. Designed to in one way or another adjuvants stimulate the immune system to respond to a particular antigen.But a number of studies have shown that the commonly used incomplete Freund’s adjuvant (IFA) may actually be hindering the performance of cancer vaccines. But it is possible that this has led to a number of cancer vaccines being dropped in phase III trials due to a mere hint at ineffectiveness.For example, Angus Dalgleish, Professor of Oncology at St George’s Hospital, London, and founder of the UK Cancer Vaccine Institute and the vaccine biotech company Onyvax, believes that his prostate cancer Onyvax could well have performed better than Dendreon’s Provenge treatment had investors had the confidence to set store in the predicted nine-month survival rates. Relatively, it is still early days for cancer vaccines and crucially developers are identifying new ways to improve the effectiveness of their vaccines. Work with non-small cell carcinoma cells has shown that they can activate CTLs, but are resistant to killing due to cytoskeletal changes.
And over the last year there’s been growing speculation as to just what the new guidelines might look like. Chiefly this is because people (thankfully) don’t drink pure alcohol, and different drinks contain different concentrations of alcohol (hence ‘ABV – alcohol by volume – the % figure on many drinks which is the proportion of pure alcohol it contains). This is because the evidence now suggests men’s and women’s risks from drinking a given amount of alcohol are about the same – although  men have a higher risk than women of immediate harms such as accidents and injuries, and women’s risk of long term illness (and premature death) is higher.
The move away from daily limits has partly been motivated by research like this on how people understand and use guidelines. Firstly, the weekly guidance also says if people drink as much as 14 units in a week, they should spread it out evenly over at least 3 days, cautioning that heavy drinking sessions increase the risk of accidents and injuries as well as long-term illnesses. And they highlight that the risk for some diseases, such as mouth, throat and breast cancers, is increased at any level of regular drinking – so the guidelines don’t represent an absolutely safe amount to drink; they’re intended to keep a person’s health risks from alcohol to a minimum. So the 14 unit limit is the level of drinking that would be expected to lead to a lifetime risk of dying from an alcohol-related condition which is similar to the harms of other routine activities, such as driving a car (to be precise, about one per cent). But as we said above, one reason for these changes is the strengthening evidence of the link between alcohol and cancer.  So what’s changed here? That’s because the effect on risk is smaller, more difficult for scientists to demonstrate  conclusively, and also prove it’s not down to other things (such as smoking or poor diet) muddying the waters.
So as well as clear guidelines and public campaigns, we also want to see the government introduce measures to tackle the price, promotion and availability of alcohol, such as minimum unit pricing, as outlined in the independent alcohol strategy Health First.
When it comes to cancer, our advice hasn’t changed – the less alcohol you drink, the lower your risk. For many people, simply tracking how much you drink can be an eye opener – there are lots of free apps and tools available, such as this one from Change4Life. We hope these new guidelines will help people understand and manage the risks of drinking alcohol. Because mouth cancer risk rises with alcohol drinking, we can assume the lifetime risk for non-drinkers is lower than these population averages.

Of course these figures are estimates – but they give a good indication of the impact of alcohol drinking at a population level. The amounts in the paper we’ve based our calculations on translate to 12, 25 and 50 grams of alcohol per day, which look like a much more sensible set of numbers to pick, but we wanted to present this in units to match with the guidelines.
It would have been of value had it set the risk here in the context of other risk factors for other cancers. Keep up the good work Cancer Research, but please don’t ally yourself with the scaremongers.
We also highlight other relevant material, debunk myths and media scares, and provide links to other helpful resources. Faller developed a method to activate silent genes within the dormant EBV virus, which resides in lymphoma cells. As throat cancer develops, it goes directly into the mucous membrane and the layers of the muscles. If the cancer does spread in adjoining tissues or in the lymph nodes, but detected early, 65% of cancer patients can be cured.
The rate of fatality for this type of cancer is very high, especially when the disease is detected in its latter stages of growth.
It all depends on whether the cancer was detected early or which area of the body is affected.

Both of which will support, guide, and inspire you toward the best possible health outcomes for you and your family. Whilst the obvious answer may be to use patient samples with cancers at earlier stages, this poses a challenge when it comes to the planning times and the length of trials, not to mention that early stage patients are less likely to have been diagnosed and so available for trial participation.Along the same lines, late stage cancer patients are likely to have undergone some variety of chemotherapy which will have seriously impeded the immune system capabilities of those who received the treatment. Researchers found that T-cells, once stimulated, were congregating around the site of the injection where the non-biodegradable IFA lingers. Moreover, many tumor cells express embryonic and developmental antigens effectively making them less susceptible targets to NKs and CTLs. But it’s also influenced by the considerable evidence that has emerged showing that even low level drinking can increase the risk of some cancers, and that this risk increases the more alcohol people drink. And while these didn’t entirely replace the weekly recommendations, confusingly the two didn’t match up – people drinking up to the maximum every day would exceed the weekly limit by 7 units. As well as suggesting people limit the amount they drink in one session, there is also advice for people to help cut the immediate risks – such as drinking more slowly. Altogether, alcohol is linked to seven types of cancer with bowel, liver and laryngeal cancers making up the total. The drinking levels we’ve picked represent people drinking within the guidelines, at around the previous weekly limit for men, and well above the recommended limits.
Non drinkers have a 5 in 1000 chance of mouth cancer (I assume they have selected mouth cancer as their worst example) which is 0.5%. Treble the chance yes but both risks are acceptable compared to other risks in everyday life.
The UKs olderst men and women (who were on the One Show they other day!) all have one thing in common: they enjoy their life and drink every single day.
The article doesn’t mention anything about environmental or genetically inherited causes. As someone who studied chemistry, it’s easy to see how drinking a spirit with 40% alcohol could affect mouth tissue far more than the equivalent amount of alcohol in a 4% beer.
However, if the cancer spreads in the outer part of the head or neck, it will be very difficult for doctors to treat. The symptoms are basically a sore throat or pain in the throat, similar to a normal bout of flu virus. These types of coughs are not caused by congestion from mucus, so Mucinex will not help treat them. Below we list just a few of the common reasons cited for the poor performance we have witnessed of many therapeutic cancer vaccines when it came to Phase III trials. This of course will limit any potential immune response the patient may exhibit as a result of the vaccine. After replacing IFA T-cells began to move towards the cancer cells without being held up at the injection site. If you cross the road on the way to work you’re at risk of being knocked down and killed. Cancer treatment for advanced cancer will usually focus on improving the cancer patient’s quality of life. But first, one thing that hasn’t changed is that the guideline amount is measured in ‘units’ of alcohol.
This will be spun as trebling your chances of getting the disease, which is true but grossly misleading. Also, we do have to drink SOMETHING or we would be dead of dehydration shortly after birth. When you eat or drink anything, the epiglottis will close in order to prevent the inhaling of liquids or foods. In some cases, this type of cancer will be detected while the patient is having a dental procedure done. The dentist may find an irregularity in the pharynx area, therefore, recommending the cancer patient to see a cancer specialist.
Other symptoms of throat cancer could be distinct changes in your voice or persistent coughing.
